Abstract
The methods of G. F. Boudreaux and T. W. Parks (1980) for hybrid FIR (finite impulse response) filter design are extended to include the IIR (infinite impulse response) structure pole location optimization problem within the dynamic programming (DP) formulation and allow multiple parallel cascade structures. In addition, the authors propose a second design method in which they apply complex basis function subset selection methods in the frequency domain to design the optimal weighted L2 hybrid approximation for a given degree of complexity. If desired, one can perform a sequence of these weighted L2 approximations to converge to the Lp approximation. Both DP and subset selection approaches are applicable over a broad class filters, including both linear- and nonlinear-phase filters.
